I've been looking through some of the Lightning Semi bits again recently. I saw a couple of UART flashers in the ftp/gitee dumps a couple of months ago and wondered about them again. I've also been in contact with someone at Lightning Semiconductor who has kindly sent me the latest... [Read more]

Some time ago I reviewed the Tuya single relay module AVATTO WSM16-W1 WiFi relay for PLN 30 , today it`s time for a similar gadget, but with two relays. All this in a small housing measuring 39mm x 39mm x 19mm. The maximum load on one channel is only 150W, but it is still worth giving... [Read more]

In this topic I will present rclone - a simple tool to synchronize/backup files. I will show here a ready-to-use script that allows you to make a copy of selected folders with just one click and the entire copy will work on an incremental basis, so it will be a much better solution... [Read more]

Everyone probably knows that before adding RAM to a computer or laptop, you should check how much RAM the motherboard can support. If the hardware does not support more RAM, there is no point in trying to add it. But are you sure? Let`s check! Recently, there was a need to increase... [Read more]

Today we are modifying another relay module for the box so that it works 100% locally, regardless of the manufacturer t described yet so that we could expand our electrode list of IoT device interiors . Purchase of WSM16-W1 The module was purchased quite cheaply - less than PLN 30:... [Read more]

I got this Smart Plug which is labeled as RMC021 on the case: That is the packaging After a little bit of opening around with an opening tool: Unscrew the screw from the neutral wire to get to rid of the case. Now you need to unsolder the plug itself from the PCB: I unsoldered the... [Read more]

I recently described the triple white light switch TS02-EU-W3 , now it`s time for its brother model, the black, double version. In addition to the process of changing the charge so that it works 100% locally, I will compare its interior with the previously discussed version. We start... [Read more]

Hello everyone and thank you at the outset for your interest in this topic. A few years ago, I described on this forum a balcony installation that still supplies my house with energy on sunny days. Over time, I reduced the energy buffer from 105Ah to 65Ah, i.e. almost by half, due... [Read more]

I bought a Smart Plug on Amazon before I even know things like OpenBeken even existed. I will post my teardown here in high hopes a clever mind can make the device supported :) The outside: (It is a little tricky to open this plug, that is why it looks so beaten up ...) After taking... [Read more]

I will show you a little interesting fact - a quite invasive but effective way to change the firmware of the cheapest WiFi-controlled socket. This socket is characterized by a low price (PLN 30) and a structure that makes it impossible to remove the board with the WiFi module from... [Read more]

OpenBeken features a deep sleep system which allows you to basically turn off the BK7231 until a certain amount of time passes (DeepSleep) or until a GPIO event occurs (like button press - PinDeepSleep). The following feature is necessary for the battery powered devices, otherwise... [Read more]

Hello everyone, for a long time I've wanted to make something cool that could be used basically every day - i.e. a useful computer desk accessory. So I came up with an internet radio with a file player on a cool OLED display. As I don't program microcontrollers every day, there are... [Read more]

Recently it appeared in the DIY section "Supervisor Detector" by @szdom. The topic aroused great interest, including mine. However, I decided to approach the problem differently - ESP was to collect data and periodically send it to the server. The main task is to detect the presence... [Read more]

This is a short programming guide for a LSPA9 socket that is using a strange TYWE2S version with non-stand pinout that does not match Tuya documentation. Video includes soldering guide and flashing method for ESP8266 with esptool.py. We'll flash Tasmota to this socket. ERRATA: On... [Read more]

I don't see that many GU10s being opened, maybe because successfully putting them back together again can be hit and miss. I've broken a couple of live/neutral pins from the chassis before and not bothered to even attempt putting it back together. A previous semi-successful attempt... [Read more]

This switch is the 2CH variant of the Gerier WiFi Switch series. It is really a small device... Start the teardown by turning the device so that you have the back on top. Use a small knife to open it from any side. Just in the middle of each side you can push a small knife in and... [Read more]

Some TuyaMCU devices combine few settings on single dpID. This doesn't necessarily mean you cannot alter the state of such dpID from OBK web page, but in all cases you will need calculator. One such device is TOMPD-63-WIFI. This is automatic circuit breaker with power meter capabilities,... [Read more]

DDP is a connectionless LED light control protocol based on UDP. DDP supports various color formats, but usually 24-bit RGB or 32-bit RGBW is used. One packet can contain multiple colors, so DDP can also be used to control LED strips such as WS2812. By using connectionless UDP (as... [Read more]

Today, as standard - we change the light switch firmware at the reader s servers and will be compatible with Home Assistant. Purchase AVATTO TS02-EU-W3 The switch can be purchased for PLN 50, which is quite a good price for a version with three relays: Packaging: Let`s see what we... [Read more]

Today it`s fun again reverse engineering . The Tuya FS-05R dimmer was sent to me by a reader asking me to decipher the UART protocol of communication between the WiFi module and the microcontroller responsible for dimming. Contrary to appearances, this is not a typical dimmer based... [Read more]

Everyone has probably heard of ChatGPT, but have you heard of ChatPDF? ChatPDF is a tool that allows you to have a "chat" with a PDF file. In this topic, I will try to use them to search for information in the catalog note of a certain port expander, we will see what the result will... [Read more]

Due to reaching 500 entries on our website Electrode list of interior IoT devices , I will remind you what this list is, how it works, why it was created and I will show you how every user can contribute to our initiative. What is the IoT Device Interior List? Our list of IoT device... [Read more]

As I have been receiving DAB+ Digital Radio for a long time, I am also struggling with reception efficiency, even though the assumptions of the DAB radio specification (DAB+) were to ensure not only digital quality, but also ensure effective reception even in difficult conditions.... [Read more]

Here I will show you step by step how to configure a TuyaMCU device, how to get dpID list, how to map dpIDs to channels and publish them to Home Assistant and how to create custom page for the device. This topic will cover most of TuyaMCU topics required to get your Tuya device running... [Read more]

Removing WB3S with soldering iron wasn't easy, cause copper is very thin and easy to torn apart. Otherwise usual flashing. I've dump tx pin on original firmware when setting color(green) //R 2024-02-23 14:13:14 WiFi received: 55AA00060005150400010125 //R 2024-02-23 14:13:15 WiFi received:... [Read more]

Here is how you can flash a T34-based wall switch with OpenBeken . This switch has no programming pads available, so desoldering T34 in QFN case is required. Purchased from AliExpress: Nothing special in the box, comes with a capacitor and some screws, and a wiring diagram. Teardown... [Read more]

Here I will show you the basics of individually addressable LEDs control in OpenBeken. Currently OpenBeken supports WS2812B LEDs and many LEDs with similiar protocols, like, for example SM16703P. In this topic I will focus on the basics of the manual LED control, I will not cover... [Read more]

This plug was already mentioned here and here is the very useful page about the LN882H. The inside is exactly the same PCB as mentioned here with another socket case and a different relay. So, why another post? I think I might give some useful information here, so I hope it's o.k.... [Read more]
